Abstract (en)
A network switch for network communications is disclosed. The switch includes a first data port interface, supporting at least one data port transmitting and receiving data at a first data rate and a second data port interface supporting a at least one data port transmitting and receiving data at a second data rate. The switch also has a CPU interface configured to communicate with a CPU and a memory management unit for communicating data from at least one of the first and second data port interfaces and a memory. It also has a communication channel for communicating data and messaging information between the first and second data port interfaces and the memory management unit and a plurality of semiconductor-implemented lookup tables including an address resolution lookup table, a multicast table, an IP multicast table and VLAN tables. One of the first and second data port interfaces is configured to determine whether an incoming data packet is a unicast packet, a multicast packet or an IP multicast packet; and one of the multicast table is searched to find egress ports for the incoming data packet.
